DHT11 digital humidity sensor, can measured humidity 20 to 90%, modules has 3-pin and used one cable for responding and transmission. DH11 also can be a thermometer, with temperature range of 0 -50 C (but not popular for use). The humidity measurements are stored in a 16-bit registers and will require a microcontroller for processing and display. 

Technical Specification

  • Measures humidity from 20 to 90% RH, accuracy at +- 5%
  • Measures temperatures from 0 C to 50 C, accuracy at +- 2
  • Power supply range is 3.0V to 5.5V, 1 mA (Max)
  • 16-bit serial data transmission, the two panels. By using a single cable read the signs (Sample Rate) every one second.
